Description
Summary:	ABSTRACTObjective To evaluate the impact as well as safety of trimanual vitrectomy versus bimanual vitrectomy in cases with complicated proliferative diabetic retinopathy (PDR) necessitating surgical intervention.Methods We designed a randomized, interventional, prospective study on 40 pseudophakic eyes suffering from tractional retinal detachment (TRD). 20 eyes of 16 cases with trimanual 23-gauge Parsplana vitrectomy (PPV) were categorized as Group A ”trimanual group.” Twenty eyes of 18 cases with bimanual 23-gauge PPV were categorized as Group B” bimanual group” in the duration between May 2021 and December 2022. All cases were under continual observation for ≥ 6 months postoperatively.Results A total of 40 eyes out of 34 cases with the mean age of cases 50.5 years (ranged between 29–69 y) in group A and 47.9 (ranged between 33–60 y) old in group B were assessed. Retinal attachment, total elimination of the pre-retinal proliferation attained in all cases of the two groups. Surgical time was statistically significant shorter in the trimanual group compared to bimanual group (p value < 0.05). Both groups gained statistically significant better vision. The mean pre-operative VA (Visual acuity) in group A was 1.75 (Log MAR) and 1.59 in group B, whereas the mean final visual outcome 6 months following operation was 0.73 in the 1st group & 0.82 in the 2nd one (p value < 0.001*).Conclusion Trimanual PPV is a safe as well as efficient approach that may ameliorate the result of vitrectomy in tractional PDR.
